What’s new

What’s new in 2.9 LTSR

Improved user audio experience during conversation pauses:

When speakers pause during calls, the call participants hear comfort noise instead of silence. This enhancement avoids call participants wondering if the call is still connected.

Quality of Experience statistics:

Added more video parameters in the Quality of Experience statistics reports.

TraceRoute information for Quality of Experience reports:

The HDX RealTime Optimization Pack now collects routing information from calls. This information is useful when troubleshooting call performance issues. TraceRoute is not supported on Android. For more information about the Microsoft TraceRoute table, see TraceRoute table.
